Answer:

An algebraic expression is a type of expression that contains a variable or variables.

Answer:

x = 26

Step-by-step explanation:

x+64 is a right angle

x+64 = 90

Subtract 64 from each side

x = 90-64

x = 26

Answer:

x = 26°.

Step-by-step explanation:

This is a complementary angle. Complementary angles are two angles that have a sum of 90°.

[tex]90-64=26.[/tex]

[tex]26+64=90.[/tex]

[tex]x=26.[/tex]

Answer:

m<ABC  = 51degrees

Step-by-step explanation:

The angle at the vertex is half the difference of the angles at the intercepted arcs. Hence;

m<B = 1/2 (arcAD - arcAC)

<ABC = 1/2(17x + 2 -(7x - 10°))

4x + 15 = 1/2(17x-7x+2+10)

2(4x+15) = 10x+12

8x + 30 = 10x+12

8x-10x = 12-30

-2x = -18

x = 18/2

x = 9

Get m<ABC

m<ABC = 4x + 15

m<ABC = 4(9) + 15

m<ABC = 36 + 15

m<ABC  = 51degrees

The measure of angle ∠ABC  = 51 degree.

Since we know that,

For a circle,

The angle at the vertex is half the difference of the angles at the intercepted arcs.

Therefore,

m∠ABD = 1/2 (arcAD - arcAC)

⇒   ∠ABC = (1/2)(17x + 2 -(7x - 10°))

⇒  4x + 15 = (1/2)(17x-7x+2+10)

⇒2(4x+15) = 10x+12

⇒ 8x + 30 = 10x+12

⇒   8x-10x = 12-30

⇒         -2x = -18

⇒             x = 18/2

⇒             x = 9

Get m∠ABC

⇒ m∠ABC = 4x + 15

⇒ m∠ABC = 4(9) + 15

⇒ m∠ABC = 36 + 15

⇒ m∠ABC  = 51 degree

Step-by-step explanation:

This problem is a bit tedious to work out all at once. The first student opens every locker so lockers 1 to 50 are open.

The second student closes every two lockers so every even locker is closed while every odd locker is open. This will repeat over and over and will take too long.

An alternative for this would be checking the factors of each number. For example, 4 has three unique factors, which are 1, 2 and 4. The number of unique factors determine whether the locker is open or closed. In this case, locker 4 will be open after all 50 students finished. Student 1 opens locker 4, student 2 closes locker 4, student 3 doesn't change locker 4 and student 4 opens locker 4. However, students 5 to 50 will never change the locker.

I can't help put all of the answers at once but this should help.

Answer:

P = -31

Step-by-step explanation:

-1 + 14p = -435

Remove the -1 by adding it from both sides.

14p = -434

Remove the 14 by dividing it from both sides.

p = -434/14

p = -31

Answer:

-31

Step-by-step explanation:

-1+14p=-435

14p=-435-(-1)

14p=-435+1

14p=-434

p=-434/14

p=-31

Hello! answer: x = 50

Step-by-step explanation:

This is a supplementary angle meaning it will add up to 180 degrees! so...

50 × 3 = 150 150 - 20 = 130

130 + 50 = 190 therefore x = 50 hope that helps!

The nth term of an arithmetic sequence is expressed as Tn = a +(n - 1)d. The 157th term of the sequence is 2180

The nth term of an arithmetic sequence is expressed as:

Tn = a +(n - 1)d

where

If -4 is the first term and 10 is the third term, then;

a = -4

a + d = 10

d = 10 - (-4)

d = 14

Determine the 157th term

T157 = -4 + (157 - 1)(14)

T157 = -4 + (156*14)

T157 = 2180

Hence the 157th term of the sequence is 2180

Answer:

AD = 6

Step-by-step explanation:

If a radius is perpendicular to a chord, then it bisects the chord.

Here XB is the radius, AC is the chord. Given XB and AC are perpendicular to each other. Therefore, XB bisects AC at D.

So,

Answer:

Two angles can be vertical and supplementary only if they add up to 90 degrees because there perpendicular.

Step-by-step explanation:

Answer:

90 + 90 = 180, 45 + 45 = 90

Step-by-step explanation:

Supplementary angles add up to 180 and to be vertical angles they need to be equal to each other so 2x = 180

x = 90

Hence both angles will be equal to 90

Complementary angles add up to 90 and as previously stated, to be vertical angles they need to be equal to each other so 2x = 90

x = 45

Hence both angles equal to 45

Mean = 14.33333333

Median = 11

Mode= 9 and 11

Range  = 42

Step-by-step explanation:

To find the mean, add all the numbers

(5+1+15+43+9+9+11+11+14+12+36+6) = 172

Divide by the number of numbers

172/12 = 14.33333333

Median is the middle number when listed from smallest to largest

1,5,6,9,9,11,11,12,14,15,36,43

Split into 2 even groups

1,5,6,9,9,11,    11,12,14,15,36,43

The middle is between 11 and 11

(11+11)/2 = 11

Mode is the number that appears mode often

This has 2 modes, 9 and 11

Range is largest number minus smallest number

Answer:

x= 15

Step-by-step explanation:

Since this is an isosceles triangle, the other angle is also 5x-6

The sum of the angles of a triangle is 180

42+ 5x-6 + 5x-6 = 180

Combine like terms

10x+30 =180

Subtract 30 from each side

10x+30-30 = 180-30

10x = 150

Divide by 10

10x/10 = 150/10

area of card board=(6+4+6+4)×10+2×6×4

=200+48

=248 in²

Answer:

B

Step-by-step explanation:

One good way to look at this is to graph both polynomials, as shown in the picture. A tip to help graph is to factor it out and work from there. For example, in x²+14x+48, we can gather that (x+6)(x+8) is the same thing, and it is easier to then graph it. Similarly, for x²+12x+36, we can factor it out as (x+6)² .

When x²+12x+36 approaches 6, it is getting really close to 0, but it stays positive. When x²+14x+48 approaches 6 from the negative side, it is also getting close to 0, but it's negative. When x²+14x+48 approaches 6 from the positive side, it is positive.

Therefore, on the negative side, there is one positive and one negative (dividing a negative by a positive is negative, and a positive by a negative is also negative) , and on the positive side, there are two positives, forming one answer.The answer is therefore B
